brahmacaryaṁ sadā rakṣed aṣṭadhā maithunaṁ pṛthak
brahmacaryaṁ sadā rakṣed aṣṭadhā maithunaṁ pṛthak |
smaraṇaṁ kīrtanaṁ keliḥ prekṣaṇaṁ guhya-bhāṣaṇam ||
saṅkalpo’dhyavasāyaś ca kriyā-niṣpattir eva ca |
etan maithunam aṣṭāṅgaṁ pravadanti manīṣiṇaḥ ||
(Dakṣa Smṛti: 7.31–33)
“One should always observe brahmacarya to the exclusion of eightfold intercourse. Remembering, mentioning, playing [alt., joking], looking, conversing privately, fancying, pursuing, and completing the act [itself]—the wise say these are the eight aspects of intercourse. The opposite of these are the eight characteristics of brahmacarya.”
